BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a mosquito and insect repellent andantibacterial tent for outdoor use.

Description of the Related Art

With the rising demand of outdoor recreational activities, camping hasbecome increasingly popular, and the number of camping sites isever-growing along with such trend. Therefore, tents that are essentialfor camping also need to continue innovating to meet requirements onleisure quality of modern people.

To be quickly and readily set up, a common conventional tent usually hasa rather simple framework, which hardly satisfies criteria of beingtotally waterproof, windproof and sturdy. Further, an outdoorenvironment with high humidity is susceptible to the growing ofmosquitoes, insects and bacteria, and all types of activities conductedunder such conditions are prone to invasions of all sorts of bacteria,mosquitoes and insects, causing infections or physical discomforts andhence lowered body functions that may lead to various undesirableconsequences. Carrying large amounts of mosquito repellent and/orsterilization supplies and devices is quite unrealistic and inconvenientfor outdoor campers. In summary, with respect to designs of conventionaltents, in addition to lacking adequate waterproofness, windproofness andsturdiness, very few of those designs can provide antibacterial as wellas mosquito and insect repellent effects.

Therefore, the architecture of a tent needs to have a sturdy andwindproof framework design, which at the same time should withstand ahumid outdoor environment susceptible to the growing of mosquitoes,insects and bacteria, and provide antibacterial and mosquito repellenteffects without relying on complicated mosquito repellent andsterilization supplies. However, most commercially available tents usesimple support structure for quick assembling or require a large amountof securing elements in order to be waterproof, windproof and sturdy,which render assembly process time-wasting and effort-consuming. Forusers who further demand mosquito and insect repellent effects, suppliesor accessories usually need to be separately purchased.

Therefore, there is a need for related industrialists to provide anideal, practical and innovated solution to solve the problems ofconventional tents to meet requirements of consumers.

The first reinforcing support 24and the second reinforcing support 26 are respectively each connectedwith the plurality of second positioning parts 142 and 143 so as to becrossed symmetrically with one another on the tent body 10 in aninverted U-shape.

As shown in FIG. 3, in one embodiment, the tent body 10 is formed by thebase cloth 32. The base cloth 32 is covered by the adhesive coatinglayer 34 and is treated with a mosquito repellent treatment with anadded mosquito repellent agent during a padding process performed by afabric forming machine during manufacture. The amount of the mosquitorepellent agent added is 4% to 6% to the fabric weight and drying isperformed under a temperature of 130.degree. C. to 150.degree. C. Duringthe padding process performed by a fabric forming machine, the basefabric 32 is also treated with a waterproofing treatment with an addedwaterproofing agent. The amount of the waterproofing agent added is 4%to 6% to the fabric weight, and drying is performed under a temperatureof 140° C. to 180° C.

The base cloth 32 of the tent body 10 is preferably a polyester latticecloth, and is added with a mosquito repellent agent made of an NK-10natural geraniol marketed under the trademark Greenfirst™ (theGreenfirst™ product series is mosquito and insect repellent products ofBREYNER). The adhesive coating layer 34 covering the base cloth 32 is anoily polyurethane coating and includes 70% to 80% polyurethane coating,10% to 20% N, N-dimethylformamide, 5% to 8% bridging agent, and 0.05% to2% antibacterial agent.

The above NK10 product is an all-natural plant antiparasitic auxiliaryagent, PROFYL NK10 is a mosquito and insect repellent auxiliary agent,and geraniol is a main active substance of a finishing agent of NK10.These substances are essences extracted from plant, so as to offervarious benefits, be effectively biodegradable, and be in balance withthe environment, as well as provide performance and safety perspectives.NK10 has an environmental effective degradation rate of 95%, and isverified by Oeko-Tex, making NK10 a safe and environmentally friendlychemical mosquito and insect repellent auxiliary agent.

After completing the two processes of the mosquito repellent treatmentand the waterproofing treatment, a coating process is performed on themosquito repellent treated and waterproof treated base cloth 32. For theformula of the adhesive coating layer, the coating glue is preferably acommon solvent-based polyurethane coating glue, which has a good bondingperformance and can easily form a cross-linking reaction with a fabric.Further, the solvent-based polyurethane coating glue is more durablethan a water-based polyurethane, with the preferred amount applied beingin the range from 10 g/m² to 40 g/m².

The foregoing antibacterial agent is an antibacterial agent from aproduct marketed under the trademark Ultra-Fresh™ of Thomson ResearchAssociates, a Canadian organization. The model of the antibacterialagent adopted in the present invention is Ultra-Fresh DM25, which is anantimicrobial, anti-fungal and anti-mite antibacterial agent that isregistered in and verified by the U.S. Environmental ProtectionAssociation (EPA). Ultra-Fresh DM25 is an antibacterial agent in asolvent-based carrier. In one preferred embodiment, the antibacterialagent is suitable in products such as a solvent-based polyurethanecoating, polyvinyl chloride and foam sponges.

The bridging agent is also a polyurethane type bridging agent, and hasbetter compatibility with the polyurethane coating glue and a strongerbonding force, providing an applied fabric with higher resistanceagainst water pressure and excellent application durability. The N,N-dimethylformamide is for diluting the polyurethane glue to anappropriate viscosity. During the coating process, a fixed amount of thesolvent-based polyurethane glue, a fixed amount of the antifungal andantibacterial agent DM-25, a fixed amount of the polyurethane bridgingagent, and a fixed amount of the N, N-dimethylformamide are preparedinto a polyurethane glue to be applied as an adhesive coating layer. Theprepared glue is then applied onto the fabric surface by knife coating(a coating device), and the fabric is placed in an oven to dry andcompletely evaporate the N, N-dimethylformamide from the prepared glue.In one preferred embodiment, the adhesive coating is applied in layersand the number of adhesive coating layers is two to three layers.
